Definitions

  • the LED arrangement may comprise in different embodiments different numbers and relative arrangements of LED elements.
  • at least two LED elements are arranged to emit light into substantially opposite directions from the traverse axis.
  • an arrangement of LED elements is preferred where at least two LEDs are arranged with their main emission directions phasing in at least substantially opposite directions from the traverse axis.
  • the main emission directions in the case of an LED element with primary optics may be defined as a maximum of a spatial intensity distribution.
  • the main emission direction will generally be perpendicular to a planar LED element.
  • the shape of the light dissipating elements 62 is relatively narrow to achieve a limited shading angle.
  • the overall shape of the upper heat dissipating structure 60 in this view is an elongate shape, i.e. the length extending parallel to the traverse axis T between the edges 64a, 64b is greater than its width, i.e. its extension to both sides of the traverse axis T.
  • the length, i.e. distance between the edges 64a, 64b is about 2.5 times larger than the width, leading to the discussed shading angle of about 50°.
  • an LED arrangement 20 comprises two individual LED elements 70 arranged at a distance from each other.
  • the LED elements 70 are arranged offset perpendicular to the traverse axis T, so that they are arranged on both sides of the heat dissipating element 262.
